Recommended Implementation Order

1. Register file;
2. Basic pipeline and ADDU instruction;
3. ADDIU and LUI instruction;
4. Handle data dependencies;
5. Jump/Branch instructions;
6. Memory accessing instructions;
7. Handle data dependencies again (pipeline controller).

Note

If you are using Vivado, after importing source files, you may need to do the following things:

1. Go to "Tools - Settings... - General - Verilog options", add src\cpu\include to search paths.
2. Select all include files in "Project Manager", then right click and click "Set Global Include".
